    Package        : cfingerd
    Problem type   : remote exploit
    Debian-specific: no
    
    Steven van Acker reported on bugtraq that the version of cfingerd (a
    configurable finger daemon) as distributed in Debian GNU/Linux 2.2
    suffers from two problems:
    
    1. The code that reads configuration files (files in which $ commands are
       expanded) copied its input to a buffer without checking for a buffer
       overflow. When the ALLOW_LINE_PARSING feature is enabled that code
       is used for reading users files as well, so local users could exploit
       this.
    
    2. There also was a printf call in the same routine that did not protect
       against printf format attacks.
    
    Since ALLOW_LINE_PARSING is enabled in the default /etc/cfingerd.conf
    local users could use this to gain root access.
    
    This has been fixed in version 1.4.1-1.2, and we recommend that you upgrade
    your cfingerd package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
